METAL H'EAD FOR BARRELS 0R KEGS.

Application filed March 3, 1916.

To all ii /tom it may camera.-

Be it known that I, JAMns 'W. BRAINARD, a citizen of the United States,residing at .littsburgh, A llegrheny county, Pennsylvania, have inventedcertain new and useful Imirove nents in Metal Heads for Barrels or kegs.of which the following is a r'ull, clear. and exact drseription,referent-e being had to the accompanying drawings forming part of thisspecification, in which:

Figure l is a top plan view showing one form of 1 improved sheet metalhead.

Fig. i. is a section on the line ll -ll of Fig. l, and showing the headapplied to a barrel or keg and Figs. 3 and 4 are views similar,respectively. to Figs. 1 and 55. but showing a niodiiiration, thesection of Fig. i. being on the line lV-----.|V of Fig. 3.

My invention is an improvement upon the barrel or keg shown in my PatentNo. 914,757, ol' March 9, 1909. The object of the present invention toprovide a sheet metal head of greutl increased strength. whieh can bereadily manufartnred from sheet metal by the use of dies. The inven'tion. has particular relation to the nirthod in which the head isreinforced o as to greatly stiller. and strengthen it at the portionsthereof which are most likely to give way in service.

Referring lirst t that form ofv my invention shown in Fws. l. and 2 thenumeral designates the body of thchead, $5 the-n1 wardly extending.flange which tits Within barrel or lceg 4, nd

the head portion of the i3 the downwardly extending flange fitting;around the outer side of the head portion, the wlfole being formedoysuitable die operations from a single piece of sheet metal.

The body portion 2 is preferably dished inwardl v, somewhat as shown,and is formed with a staror spider-shaped reinf0rcement. Thisreinforcement is formed by pressing), inwardly the eentnal portion ofthe (3. with a plurality of slaved radiating depressed ribs 7 which preerably extend to points adjac nt to the .base of the flange 3.

Experience has shown that the central portion of these heads are mostapt to give way in service. This I effectively prevent by the provisionof the central 'reinforee 6. while the radiatil'ir ribs 7 st'iii'en andrein force the entire body.

The form ofmy invention shown in Figs.

Specification of Letters Patent.

Patented July 30, 1918.

Serial No. 82.853.

3 and 4 is similar to that shown in Figs. 1. and 2, except that insteadof pressing the metal inwardly to form the central reinforce 6 and theradiating ribs, the operation is reversed and the metal is pressed out--wardly, forming these reinforces on the outer surface of the body.Similar referent-e eharucters to those used in Figs. 1. and 2 areapplied to corresponding parts in Figs. 3 and l. with the sullix a.

In these figures I have also shown the lower edge of the flange 5 asformed with :1 rolled bead 8, thus doing away with a raw edge at thispoint and preventing craeking or splitting of the head when driving itover the chime of the barrel. This bead liiay also be used on the formshown in Figs. 1 and 2. ll ivill be noted that in both forms of myinvention the body portion is continuously di hed across its diameter;and that the rentral reinforce and the radial reinforcing ribs arepressed out of the general plane of curvature of the dishing. alsopreferably taper the radiating ribs so that the 1 will be deepest andwidert at the point where they join the central reinforce, with agradual decrease in both depth and width toward their outer ends.

M invention provides a greatly improved metr'l head for barrels or kegswidth can he maiuifnctured at a relatively small cost by simple dieforming operations. and which is strbngg and durable in service. Theneed for end hooks for the barrel or k g is done away with, by mycombined head and hoop.

1 claim:

1. As a new article of manufaeture. a barrel or keg, head formed from asheet metal blank and having a to portion dished inwardly acrosssubstantially its full diameter, the central portion of the bodv havingthe metal thereof pressed out of the general plane of curvature, saidhead having an annular flange at itsonter edge, there being an annularrecess of tapered cross section in the flange formed by bending thematerial upon itself and arranged to receive the chime of the barrel,and the metal being also shaped to form a pier lity of hollow taperedradiating ribs the depressions of which open at their inner ends intothe depression of the fleutral reiuforrv, said depressions tapering inwidth and depth from the rcntral portion toward the edge of the head.substantially. as d'escri bed I 2. As a new article of manufacture, abarre] or keg head formed from a sheet metal blank and havin a topportion dished inwurdly across sulistnntially its full diame ter, thecentral portion of the body having the metal thereof pressed out of thegeneral plane of curvature, said head having an annuler flange at itsouter edge, there being an annular recess of tapered cross section inthe flange formed by bending the material u on itself and arranged toreceive the chime oi the barrel, and the metal being so shaped to form alurality of hollow tapered rudiating ribs tlie depressions of which openat their inner ends into the depression of the central reinforce, saidClGPICSSlOHs tapering in width and depth from the central portion towardthe edge of the head and said depres sions merging into the generalplane of cul'\' ature of the dished portion adjacent to the edge.

3. A metallic head for staved barrels, kegs and the like, said headbeing formed froin a sheet met-ii hlnnk dished inwardly over the fulldiameter of the barrel and having an outwardly flared flange risingt'roni the ed 0 of the dished portion and adapted 'to it closely withinthe ehinie oi the harroh said flange being bent horizontally its outeredge and thenre haekwardly to form a ehiine hoop portion, said flangeand hoop portion forming a wedging seat for the chime and said flangeulSo forming an ahutment to resist outward llexure of the head,substantially as described.
